M6A2, aftermarket Ceracoted (dont know if that makes a difference by making it tight in the upper or anything).
Took it out to fire for first time.
Put my stuff on it , an Aimpoint PRO and a AFG (I like both an AFG and a VFG depending on my stance at the time)
Went thru Zeroing the Irons and the AIMpoint PRO with PMC Bronze and then XTac.
Went w/o a hitch.
The went to battle drills and more rapid fire.
At this point I am out of PMC Bronze and only firing M193 XTac.
However I get a failure to feed on the second to last round.
twice.
basically the round was halfway inserted and the bolt force it againt the feedramp of the chamber by its middle.
Round fell out easily after locking bolt to the rear.
Thinking it might be a magazine (I own a mix of Magpul and Gen 2 TAPCOS, it was the TAPCOs I had with me today never had any problem before and both magazines were fairly new)
ity happend a total of 3 times.
I was thinking it was the magazines even though they look perfect and are fairly new and i use them on my other LWRC w/o any problems of any kind.
I attached pics of the rounds too.
but form looking at the rounds it looks like it wasnt magazines...
From looking at the rounds it looks like the BCG and/or bolt was not back far enough when the round came up.
So it grabbed it incompletely
from looking at the rounds the LGS AR gurus thought the bolt had not ridden back all the way.
That for some reason the ammo might have been too soft (tho I was shooting XTac, which while mnot being Lake City is certainly not a soft round)
recommended switching from a H2 to an H1 buffer.
( I have one at home which I will put in before i go back)
I had a similiar failure mode only once before when I was shooitng 223 out of a daniel defense that had an H buffer and the previous owner had put in a too big ( rifle?) spring.
Back then was able to fix it by changing out the spring to carbine spring and the buffer to carbine buffer.
HI rez pics of the rounds are attached.
Fsailure happend w/ 2 different magazines however both at the 2nd ot last round.
